UMX Ultrix wheel

thingiverse

Here's a wheel for the UMX Ultrix. It fits on the stock wire skid, which needs to be twisted 90 degrees. The end of the skid also needs to be straightened so the wheel will slide on the wire. CAUTION... several of us have snapped the skid while trying to twist it 90 degrees. Mine did not snap. If this is a problem, see my all plastic design (search for Ultrix and you'll find it). Install the wheel so the side with the extended hub goes on first and rides against the bend in the skid. The wheel is retained with the wheel retainer. It was designed to be a tight press fit but due to its size, it might print loose enough to come off. If too loose, it can be secured with a drop of CA. I printed in standard PLA at 220 degrees C, with the bed at 60 degrees C.
